摘要

A compact, two-band bandpass filter, exploiting dual-layer hexagonal shape, open-loop folded, step-impedance-resonators (SIR), for Bluetooth and WLAN applications, using low temperature co-fired ceramic (LTCC) technology, has been designed and fabricated. The filter is composed of three hexagonal shape open-loop SIRs embedded in multilayer thin ceramic to produce a compact size. The proposed topology is demonstrated with a design operating at 2.40 GHz with a bandwidth of 400 MHz and 5.20 GHz with a bandwidth of 200 MHz. More than 30 dB of spurious suppression from 5.8 to 7 GHz is demonstrated in the experimental results.
